why does mariam finally say yes in the marriage ceremony to rasheed?

Marium really has no choice. Mariam asks if she could live with Mullah Faizullah, but the wives refuse. The thought of household chores and sexual intimacy disgusts Mariam. Mariam learns that she is to be married tomorrow, and Jalil has already agreed. Mariam protests, but Jalil does nothing to stop the arrangement. Afsoon locks Mariam in her room for the night.
